1 cent is 2 ^1/1200 = 1.000577789 times. One octave is 1200 cents. At n cents, it is 2 times {= (1.000577789) ⁿ } of the original frequency. Therefore, the frequency of the sound of n cents higher than the sound of the basic frequency Fo [Hz] can be obtained by the following formula.

Fn [Hz] = Fo × 2 ^{n / 1200}

The actual frequency for the cents at this time is as shown in Table 4.19.

Table 4.19 Actual frequency for cents

0	1.000000000
100	1.059463094
200	1.122462048
300	1.189207115
400	1.259921050
500	1.334839854
600	1.414213562
700	1.498307077
800	1.587401052
900	1.681792830
1000	1.781797436
1100	1.887748625
1200	2.000000000

Next, the setting method of "FNS" and "OCT" will be explained as an example when the C4 sound is sampled at 44.1KHz.
∙ The "FNS" value for P [Cent] can be calculated using the following formula.

FNS = 2 ¹⁰ × (2 ^{P / 1200} -1)

∙ From this equation, it is possible to output at any frequency by setting each parameter as shown in Table 4.20.
